Abstract

Abstract : The hydride complexes [RuH{κ 3 ( N, N, N )‐Tp}(PPh3 )(pta)] (1 ) and [RuH{κ 3 ( N, N, N )‐Tpms}(pta)2 ] (3 ) [Tp = hydridotris(pyrazol‐1‐yl)borate, Tpms = tris(pyrazol‐1‐yl)methanesulfonate, pta = 1, 3, 5‐triaza‐7‐phosphatricyclo[3.3.1.1 3, 7 ]decane] reacted with alkynes to form the corresponding neutral alkenyl complexes through insertion reactions. The addition of HBF4 to the hydride complex [RuH{κ 3 ( N, N, N )‐Tp}(PPh3 )(pta)] (1 ) led to a coordinatively unsaturated complex through the loss of hydrogen. The free coordination site can be occupied by different groups, such as BF4 or NCMe. Abstract : The hydride complexes [RuH{κ 3 ( N, N, N )‐Tp}(PPh3 )(pta)] and [RuH{κ 3 ( N, N, N )‐Tpms}(pta)2 ] react with alkynes to form neutral alkenyl complexes. The complex [RuH{κ 3 ( N, N, N )‐Tp}(PPh3 )(pta)] also reacts with HBF4 to give [Ru(FBF3 ){κ 3 ( N, N, N )‐Tp}(PPh3 )(pta)]. A new ruthenium complex bearing a κ 2 ( N, N )‐Tpms ligand has been isolated and fully characterized.
